Question

GeoStyle geoStyle = new GeoStyle();
                               geoStyle.LineColor = Color.Red;
                               geoStyle.MarkerSize = new Size2D(16, 16);
                               geoStyle.MarkerSymbolID = 100; // 点状符号编码100，一面红旗;
                               GeoPoint m_GeoP = new GeoPoint();
                               m_GeoP.X = 111.34;
                               m_GeoP.Y = 36.11;                            
                               m_GeoP.Style = geoStyle;
                               m_mapControl.Map.TrackingLayer.Add(m_GeoP, "100");

                               GeoStyle3D m_geoStyle3D = new GeoStyle3D();
                               m_geoStyle3D.LineColor = Color.Red;   
                               m_geoStyle3D.MarkerSymbolID = 100;//
                               GeoPoint3D m_GeoP3D = new GeoPoint3D();
                               m_Geo3P.X =111.34;
                               m_Geo3P.Y = 36.11;
                    m_Geo3P.Y = 36.11;
                               m_Geo3P.Style3D = m_geoStyle3D;
                              this.m_SceneControl.Scene.TrackingLayer.Add(m_Geo3P,"100");   
 
请问，在二维地图中能够标会出点状符号红旗，在三维中只是一个白色的点，这是问什么？

Answer 1

您好，三维场景标绘和二维地图标绘的使用操作是有所不同的。

三维场景标绘您可以查看帮助文档中ActionGraphicObject3D 类相关，他与二维地图标绘ActionGraphicObject类是不一样的。

希望可以帮助到您！
